Solution Notes
The following configuration (OSGi Configuration Admin) option has been added for Liferay Message Bus:

Control Panel - Configuration - System Settings - Foundation - Destination Worker Configuration. You can create entries by specifying the following attributes:

• Destination Name: For example liferay/background_task_status
• Max queue size: Set the maximum number of requests allowed in the worker queue before it rejects additional requests. If set to -1, then by default, the value is Integer.MAX_VALUE.
• Worker core size: Set the number of worker threads allocated to the destination.
• Worker max size: Set the maximum number of worker threads allocated to the destination.

Default Background Task destination configurations are the following after this fix:

• liferay/background_task: Worker core size: 5, Worker max size: 10
• liferay/background_task_status: Worker core size: 1, Worker max size: 1
